GAUGE TOOL.

Application filed November This invention relates to gauges embodying a carriage adapted to accommodate work of different configurations totdeter mine the centers thereof.

Another object of the invention comprehends a frame to slidably mount the carriage to support work of different lengths.

A further object of the invention contemplates a marking bar adapted to be. swung into position for so against one side of the work for marking the center thereof.

More specifically stated the marking bar is adapted to be swung at angles to a. vertical to mark work having battered or rounded ends.

The invention further consists of scril'iers and punch markers adapted to be carried upon the frame adjacent the markir ar withinconvenient reach of a machil Vith the above and. other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described,

illustrated in the accompanying drawings and pointed out in theappended claims.

1 In the drawings:

Figure 1 is a side elevation of the inven tionv while in use.

Figure 2 is a top plan view thereof.

Figures 3 and 4 are end elevations of the invention.

Figure 5 is a fragmentary side elevation of the invention while in use for scribing the centers of elbows and other rounded fit-- tings.

Figure 6 is a detail view taken through the frame and illustrating the mounting of a scribing pin therein.

Figures 7 and 8 are perspectives of a punch marker and scribing pin respectively.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference characters 10 indicate spaced parallel tubular members having connection at the ends thereof with transversely disposed spacing plates 11 and 12 respectively.

The carriage, as mentioned in the foregoing consists of plate members 13 provided with right-angularly disposed long and short sleeve portions 14 and 15 respectively, slidably mounted upon the tubular members 10 and disposed in staggered relation thereon.

The upper portions of the plates have 4, 1927. Serial No. 231,121.

portions removed toprovide V-shaped seats 16, the purpose of which will be presently apparent.

An upstanding portion 17 carried by the spacing plate 12 is provided with an outwardly and upwardly extending apertured car 18 adapted to receive the shank of a fastening element- 19 therethrough. A spacing washer20 and ear 21 carried upon a marking bar 22 also receives the common fasten= .ing element, which is in turn provided with a wing nut 23 upon the tapped end thereof to facilitate the loosening and tightening of the juncture of association of the marking bar to set and lock the same in a desired position. i

Scribers 24 and center punchers 25,- eaclr being provided with rounded heads 26 have the shanks thereof received Within the ends of the tubular members 10 adjacent the spacing plate 12. Said shanks are retained against displacement through the instrumentality of spring lingers 27 carried with in the bores of the tubular members.

The plate members 13 are, in addition, provided with portions removed as illustrated at 28 to accommodate the marking bar 22 when the latter is swung to occupy a horizontal position, not shown, when the device is not in use to protect the marking bar.

The invention is primarily adapted for determining, from asgiven piece of stock. whether bent or sprung, if a. smaller shaft or piece of stock may be turned from the damaged stock by measuring froint'he ce'gnter thereof.

The centering is accomplished in the following manner:

As illustratedin Figure 1 of the draw- .ings, the work is laid upon the V-shaped seats 16 of the plate members 13. The weightof the work will move the same to ward the apices of said seats. The plate members being adjustable to accommodate werk of different lengths. If the work exposes a straight out extremity toward the marking bar 22 and the same is moved to occupy the position in juxtaposition there with, the scribing pin 24 is then witl'idrawn from one of the tubular members 11 and a line drawn against the left hand side of the marking bar 22. The Work is then rotated approximately that of a quarter turn and the work again marked with the scribing pin. The inner section of the scribing marks is then struck with the pointed end of the punch mark 25, thereby indicating the center at one end of the work.

By the same token, if a battered end upon the work were exposed, as illustrated in the dotted line position in Figure 1 of the drawings, toward the marking bar 22, said bar, by the adjustment all'orded through the fastoning element 19 could be swung at an angle to occupy the particular dotted line position hereby the correct center of the work at the particular end could be readily ascertained.

The same position of the marking bar is occupied when determining the center of an elbow or like fitting, as best illustrated in Figure 5 of the drawings.

As illustrated in Figures 2 and 3 of the drawings, the marking bar 22 is beveled inwardly upon the left hand side thereof, as indicated at 29, to guide the pointed extremity of the scribing pin :24 toward the center line of the work. The face of the marking bar 22 exposed to the work is, in addition, beveled upon the right hand corner, as indicated at 30, to lie flush against work having obtuse extremities. The stock or work does not have to be trued up at the end to ascertain the center thereof. By setting the plate members 13 back a sullicient distance from the marking bar, shafts battered, ball shaped on the ends provided with pipe fittings, pieces with ends beveled, centers of eye ends of eye bolts, tapered shafts, shafts with eccentrics on ends, or in fact any complicated or irregular shape can be handled as easily and as quickly as the more simple shapes.

As mentioned in the foregoing, the specific configuration of the marking bar and the mounting therefor facilitate inclining of the bar until it coincides with rounded or beveled end work.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having thus described the invention, what is claimed is 1. A gauge tool comprising a frame, a carriage slidably mounted thereon, and a marking bar swingably mounted upon the frame being adapted to be swung toward and away from the adjacent end of the work to determine the center thereof when sup ported upon the carriage.

.2. A gauge tool comprising a frame having spacing plates upon the ends thereof, carriage plates slidably mounted upon the frame between the spacing plates. the carriage plates being further provided with V- shaped seats within the upper ends thereof to support the work, and a marking bar pivoted. on one of the spacing plates being adapted to be swung toward the adjacent end of the work supported within the seats.

3. A gauge tool comprising tubular memhers, spacing plates carried upon the ends thereof, carriage plates having long and short sleeve portions adjacent the lower ends thereof slidably mounting the same upon the tubular members, the sleeves being oppositely disposed to permit disposition of the carriage plates in juxtaposition, the rarriage plates being further provided with V- shaped seats within their upper ends to support the work, and a marking bar pivoted upon one of the spacing plates being adapted to be swung in juxtaposition to the work supported within the seats.

4. A guage tool comprising tubular members, spacing plates 'arried upon the ends thereof, carriage plates provided with long and short sleeve members adjacent the lower portions thereof slidably mounted upon the tubular members, the carriage plates having V-shaped seats within their upper ends, said sleeve members being oppositely disposed to position the carriage plates in close proximity, an ear upstanding from one of the spacing plates, a marking bar having connection with and adapted for swinging movement upon said ear, and the faces of the marking bar being adapted to lie flush against work ends of different shapes supported in said V-shaped seats and to facilitate scribing of center lines thereon for punch marking.

In testimony whereof I ailix my signature.
